Methods and systems for identifying, handling, and debugging a hung thread

A device, comprising:

• a user interface;
• a network interface;
• a processing system of the device, comprising one or more processors, the processing system being in communication with the user interface and the network interface;
• an application, comprising a plurality of threads, executed by the processing system of the device;
• a thread monitor module executed by the processing system of the device that monitors for any hung threads within the plurality of threads being executed by the processing system of the device, wherein the thread monitor module is executed as a first thread of the plurality of threads and is configured to:
• receive a monitoring initialization message from a second thread of the plurality of threads to initiate thread monitoring of the second thread, wherein the monitoring initialization message comprises:
• a thread identifier of the second thread;
• and an update frequency time period;
• register a defined signal with an operating system of the device;
• in response to the monitoring initialization message, track the second thread by determining whether an update from the second thread has been received within the update frequency time period indicated in the monitoring initialization message;
• receive, from the second thread, the update that indicates the second thread is not hung;
• determine that at least the update frequency time period has elapsed since the update has been received from the second thread, thereby identifying the second thread as the hung thread;
• in response to determining that at least the update frequency time period has elapsed since the update has been received from the second thread, raise the defined signal on the hung thread;
• and
• a management thread, executed as part of the plurality of threads, configured to:
• receive, from the thread monitor module, an indication of the thread identifier of the hung thread;
• and
• receive an action message indicating an action to perform to remediate the hung thread, wherein the action is selected from the group consisting of:
• restarting the application;
• restarting the device on which the application and the hung thread is executing;
• starting the second thread;
• and ending execution of the second thread.

A non-transitory processor-readable medium comprising processor-readable instructions configured to cause one or more processors of a device to:

• execute, a first thread of a plurality of threads, the first thread being a thread monitor module, wherein the thread monitor module monitors for hung threads within the plurality of threads;
• receive a monitoring initialization message from a second thread of the plurality of threads, wherein the monitoring initialization message initiates thread monitoring of the second thread and the monitoring initialization message comprises:
• a thread identifier of the second thread;
• and an update frequency time period;
• register a defined signal with an operating system;
• in response to the monitoring initialization message, track the second thread by determining whether an update from the second thread has been received within the update frequency time period indicated in the monitoring initialization message;
• receive, from the thread, the update that indicates the second thread is not hung;
• determine that at least the update frequency time period has elapsed since the update has been received from the second thread, thereby identifying the second thread as a hung thread;
• in response to determining that at least the update frequency time period has elapsed since the update has been received from the second thread, raise a defined signal on the hung thread;
• and
• receive, by a management thread of the plurality of threads, from the thread monitor module, an indication of the thread identifier of the hung thread;
• and
• receive an action message indicating an action to perform to remediate the hung thread, wherein the action is selected from the group consisting of:
• restarting an application;
• restarting the device on which the application and the hung thread is executing;
• restarting the second thread;
• and ending execution of the second thread.
